APPARATUS FOR REGULATING THE FLOW OF GAS OR FLUID BY STEAM-PRESSURE.

SPECIFICATION forming part of Letters Patent No. 416,061, dated November26, 1889.

Application filed February 9, 1889.

To all whom it may concern.-

Be it known that I, GEORGE CoRYDoN JACKSON, a citizen of the UnitedStates, residing at Dushore, in the county of Sullivan and State ofPennsylvania, have invented certain new and useful Improvements inApparatus for Regulating the Flow of Gas or Fluid by Steam-Pressure; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to certain improvements in means for regulating theflow of gas or gasoline or other fluid to the burners of a furnace,boiler, or heater in which a gaseous or fluid fuel is employed; and ithas for its object to so construct, arrange, and combine the parts thatby simple and efficient means the flow of the fuel to the burners willbe automatically regulated, so that a comparative substantially uniformtemperature and pressure will be maintained, the volume of fuel, andconsequently the intensity of the flame, varying with and beingcontrolled by the pressure of steam in the boiler or heater, so thatwhen a predetermined pressure or the pressure and temperature reduced,there being, however, a sufficient supply of fuel to maintain a flameeven though the main supply of fuel be entirely out olf.

To the accomplishment of the above and such other objects as mayhereinafter appear the means devised and employed for effecting themwill now be described, reference being had to the accompanying drawings,forming a part hereof. v

Figure 1 is a side view of the mechanism with some parts in section andothers broken away. Fig. 2 is a plan view of Fig. 1, showing a series ofpipes and levers operated from a single steam-chamber. Fig. 3 is a sideview showing a single lever used in connection with the other parts.Fig. 4 is a modified form showing the steam-chamber placed above theberial Nof299,240. (-No model.)

supply-pipe. Fig. 5 is another modification used for higlrpressuresteam, parts being in section. Fig. 6 shows how a piston may be usedinstead of a diaphragm in the steamchamber. 1

In the drawings, the letter A designates a main supply-pipe for thepassage of the fluid,

to shut oif the flow of fuel either wholly or partially as the lever israised more or less.

In Figs. 1 and 30f the drawings I have shown the lever connecteddirectly with the cook or valve II, the cock or valve being open whenthe lever is in its normal position. The movement of the lever in onedirection is controlled by the pressure of steam againstthe bottom ofthe diaphragm E or its equivalent, the steam being admitted to thechamber D through the pipe I, which leads from the boiler of the furnaceto which the flow of fuel is regulated. pressure at which the steamshall move the diaphragm or its equivalent to move the lever is fixed bythe adjustment of the weight J 011 the extended arm of the lever G. Ifdesired, a weight may be also applied to the opposite end of the lever.

It will be seen from the description so far given that when thetemperature of the furnace reaches a higher point than is desirable andthe pressure of steam is correspondingly raised the increased pressureof the steam in the chamber D will, through the diaphragm, stem, andlever, move the cook or valve in the main supply-pipe and cut off whollyor partially the flow of the fuel, and thus lower the fire, andconsequently the temperature, and then as the pressure of the steamfalls the weighted lever returns to its normal po- The predeterminedsition and the flow of fuel to the burner increases. By suchconstruction and operation the flow of fuel and the degree oftemperature are controlled and regulated.

In order that-the flame of the burner may not be entirely extinguishedwhen the supply through the main pipe is cut off by the stopcock orvalve H, a by-pass is provided, so that there may pass a sufficient flowof fuel to keep up the flame. This by-pass is designated by the letterL, and is a branch pipe communicating with the main supply-pipe on eachside of the cock or valve H in the main pipe, so that when the flow iscut off by the cock H a sufficient quantity of fuel to keep up the firewill fiow through. the by-pass, and thence through the main pipe to theburner. This by-pass is provided with a valve or cock M, so that theflow of the fuel through it may be regulated or entirely out off.

It will be observed that the arrangement and combination of partsdescribed are such as to bring them into a narrow compass of space andto actuate the stopcock in the main supply-pipe through a weightedlever, which is intermediate of the stop-cock and the diaphragm, so thatas a consequence the action on the stop-cock is sensitive and prompt,the parts are not liable to get out of order, and the flow of fuel maybe entirely or partially cut off, as desired, through both the main pipeand also the by-pass. The arrangement also enables several main pipes tobe operated in the same manner as a single main pipe from a singlediaphragm or steam-chamber, as illustrated in the top plan view shown inFig.2 of the drawings. In that figure is illustrated a series of fourmain pipes, although there may be more or less, each one constructedwith a cock and by-pass, as hereinbefore described, and the seriessupported in the laterally-extending arms 0 of the bracket or standard0, each main pipe of the series having a lever G, connecting with the oftheir length with a frame or cross-bar N,

which will be bolted, as illustrated, to the lever, which is pivotallyconnected, as previously described, to the stem F, so that when thatlever is raised or lowered, as previously described, the whole series oflevers will be raised or lowered, and the cocks or valves in the severalpipes thus operated simultaneously, theweight on the main leveranswering for all the other levers connected with it. It is obvious,however, without description or illustration that each lever might haveits own individual weight. It will also be understood that while I haveshown and claim the preferred form of connection of the several leversto the stem F, still I do not mean to restrict myself thereto, as theinvention includes other modes or means for operating the series oflevers from the one diaphragmchamber. It is also apparent that insteadof having the diaphragm-chamber located below the main supply-pipe itmay be above it, as shown in Fig. 4, and in that case the lever G may beconnected to the cock or valve II by the two rods 0 and P. The operationwill be the same as described under the preferred construction, and thelever will be intermediate of the cock to the main supply-pipe and thediaphragm to the chamber D, so as to transmit motion in the same way.

For furnaces or boilers where high-pressure steam is generated I preferto employ a system of compound levers, as illustrated in Fig. 5, inwhich case the top or cover to the chamber D may be omitted, thediaphragm E itself constituting the top. In this form the stem F hasconnected to it the lever G, pivoted or fulcrunied to the standard P atone end, and at the other end connected by the rod or link Q, to theweighted lever G, which will be connected at Z) to the stopcock orvvalve of the main supply-pipe A, supported by the bracket 0. The actionof the parts described to regulate the flow of the fuel is the same asin the other forms hereinbefore described. The connection of thediaphragm is with the stop-cock in the main pipe, and the lever G,connected with the diaphragm and the cock or valve, is intermediate ofsaid parts. The standard P may have an overhanging arm or projection Q',in which will work a set-screw S, which may be adjusted to regulate thethrow of the lever G.

Instead of the diaphragm E, I may employ a piston T, (shown'in Fig. 6,)acted on by the steam in chamber D in the same manner as diaphragm E,and in that sense treated as the equivalent of the diaphragm.

If desired, cocks may be placed in the main pipes, so as to cut off anyone pipe, while th others may remain in operation.

I do not confine myself to the bypass and cook or valve for the mainpipe being formed in one piece, with a coupling between sections of thepipe; but I consider such construction as the preferred form, because itenables those parts to be quickly applied and renders the constructionas a whole much simpler and stronger than otherwise.

This invention is particularly well adapted for heaters for warmingbuildings in which heaters gas or gasoline or other fluid fuel is usedto generate heat; but I do not confine myself to such application of it,as it may be used wherever it will work to satisfaction; nor do I meanto confine myself to details of construction where equivalentconstructions will accomplish the same results, although I do claim thedetails in addition to equivalent constructions and arrangements.

Instead of connecting the diaphragm-chamber D with the steam-space of aboiler, it is obvious that it may be connected with the water-spacebelow the water-line, and thus it is evident that either steam or watermay be used to move the diaphragm or piston, either of which constitutesa moving-head.

Having described my invention and set forth its merits, what I claimis 1. The combination, With the diaphragmchamber and its moving-stemactuated by a moving-head, of the fuel-supply pipe provided with acontrolling cock or valve, a bypass connecting the main pipe on oppositesides of the cook or valve of said main pipe,

and a lever connected with the diaphragm-- stem and with the cock orvalve, so as to turn with the cock or valve as apivot between the twopoints of connection between the bypass and main supply-pipe,substantially as and for the purposes set forth,

2. The combination, With a diaphragmchamber and its moving-stem actuatedby a moving-head, of a bracket supported from said chamber, afuel-supply pipe supported by said bracket and provided with a cock orvalve, a lever intermediate of said cock and stem and connecting Withboth of them, and a valve-controlled by-pass communicating With thefuel-supply pipe on opposite sides of its cook or valve, substantiallyas and for the purposes set forth;

E. The" combination of the diaphragmchamber and its moving-stem actuatedby a moving-head, a fuel-supply pipe, a coupling for sections of saidpipe, formed with a cook or valve to control the flow of fuel throughthe supply-pipe and having a valve-controlled by-pass communicating withthe interior of the coupling 011 opposite sides of its valve, and alever connected with said stem and said main controlling-valve of thefuel-supply-pipe coupling, substantially as and for the purposes setforth.

4:. The combination, with a steam-chamber and its moving-stem actuatedby a movinghead, of a series of fuel-supply pipes, each provided witharegulating cock or valve and a series of levers connecting the cocks ofthe several pipes with said moving-stem to actuate the cocks in theseveral pipes from the one diaphragm-chamber, substantially as and forthe purposes set forth.

5. The combination, with a steam-chamber and its moving-stem actuated bya movinghead, of a series of fuel-supply pipes, each provided with aregulating cock or valve, and a lever connected with said stem and withthe cooks to the several fuel-pipes to simultaneously actuate theseveral cocks from the same diaphragm-chamber, substantially as and forthe purposes described.

In testimony whereof I affix my signature in presence of two Witnesses.
